. vomims, (01. 139-88) This, invention relates to improvements in loom harness, with particular reference tothe connectors for theheddle frames'of such-harness. More specifically, the invention comprises an improved form of harness connector with novel features of. construction, whichmay be used 'for heavy frames particularly; v

, The harness connectors heretofore most commonly used do not combine adequate strength 1 with provision for ease of mounting and adjustme u, It is anlobjejct of this invention, therefore, to overcome the difficulties heretofore encounteredinthese. respects, t

,A; further object of the invention is to provide aharne'ssfconnector which is sturdy in construction' and suitable forfheavyframes, and which at the same time is not complicated in its details. Afurtherobjectof the invention is to provide a harness connector whichmay beeasily applied to. orremovedfrom aharness frame, yet which willbe securely attached to the frame'whenin Apfurther object of the invention is to provide a clamping structure for use with a harness'oonhector, which will provide adequate bearing surfaces between p'ivotally mounted Portions thereof. Additional objectsofthe invention will be obvious from the specificationand claims.

In the accompanying drawing, wherein is shown a preferred embodiment of the invention,

Figure 1 is a front elevation of a harness frame with the invention applied thereto; 1 L Fig. 2 is a rear elevation, on a somewhat larger scale than Fig. 1, of the harness frame connector;

Fig. 3 is a front elevation similar to Fig. 2;

,Fig. 4 is an end elevation, with the rail of the harness frame shown invertical section on the line 4 -4 of Fig, 1; and .e Fig. 5 is a horizontal section through a portion'of the connector, taken onthe line 5-5 of j nwm, of course, be understood thatthe description and drawing herein containedare illustrativemerely, and that various modifications andchan'ges may be made in the structure disclosed without departing from the spirit of the invention.

Referring more particularly to the drawing, it will be seen that there is provided a harness frame of a usual type, having horizontal rails l0 connected by end members ll. Rods I 2, which are mounted in the frame in any preferred manner, carry the heddles l3 thereon.

Connectors embodying the invention are shown on the upper and lower rails I 0. While two connectors have been shown at the top' and at the bottom, respectively, additional *connectorsmaybe used if desired.

Each connector comprises a rail engaging mem-- ber l4, which may embrace arail'on three sides"; and is under an initial gripping tension when applied to the rail. This rail engaging membeiglfi, whichispreferably, made from strap metalfis generally U-shaped when viewed from the one; and hasflat walls IS in conformitywith the parallel front and rearfaces of the-rail Ill. The walls [5 are joined by,a portion lfifi which may be shaped toconform to the inneredge surface of the top or'bottom rail, as the case may be. The flat walls l5 have offset portions ll integrally connected therewith, and these offset portions H merge with end portionsl8 which are spaced apart, project beyond the rail, and are substantiallypara'llel to the walls l5. The offset portions I! may also contact and hold therail as holes therein for the reception of portions of the clamping structure ashereinafter pointed out.

A harness strap receiving member "l9 'i's also provided. This member l9 may havefan"elongated part with an opening therein, as shown at20, for the reception of a flat harnessstrap (not shown), or may have a toroidalfpart 2| with a circular aperture therethrough', as shown at 22. This aperture may take any preferred 20. shown in Fig. 4. The end portions l8 have alined 1 form, in accordance with the type of harness strap employed, or if desired a hook may be provided. V V

Thejstrap receiving member l9 has a bearing collar 23, formed with parallel fiat faces for reception between theendportions l8 of the rail engagingj'ld, and has an opening therethrough for alinement with the openings in the aforesaid end portions IS. The metal surrounding the opening serves'as a bearing surface, as hereinafter pointed out,

Clamping structure, the details of which may be seen in Fig, 5, is provided for holding the railengaging member l4 and the harness strap receiving member IS in the desired assembled relationship. The clamping structure includes a and at the same time permit easy removal of the bearing pin 24, projections 26 may be punched or otherwise formed in the adjacent end portion of the rail engaging member Hi.

The bearing pin 24 extends through the apertures in the end portions I8, and through the opening in the collar 23.

A machine bolt or screw 21, with a slotted head 28 which does not project beyond the harness strap receiving member 2|, has threads which engage the internally threaded portion of the bearing pin 24. This machine screw 2? serves to hold the cylindrical bearing pin 24 in position. A washer 29 is interposed between the head 28 of the machine screw 21 and the adjacent end portion I8.

The manner of attaching the connector to a harness frame, and the action thereof when in use, will now be described.

The rail engaging member I4 is applied to the rail [0 by springing the end portions l8 apart so that they may pass over the front and rear faces of the rail. This member M then engages the rail embracing and gripping the same by reason of the initial gripping tension thereof as well as by reason of the ofiset portions l? which tend to guide the member to its final position on the rail and maintain it there by their own confining action. No undue or undesired movement of the member I4 with respect to the rail I!) will occur .'hen the rail engaging member has been brought to its gripping position. The rail engaging member 14, even though made of onepiece of metal, may be applied to a heddle frame having heddles mounted therein with the same facility as to a frame without heddles.

The collar 23- is then placed between the end portions IS, with its opening in alinement with the apertures in said end portions, and the bearing pin '24 of the clamping structure is inserted. The clampingstructure may then be tightened by means of the machine screw 21, to secure the collar 23 under the desired degree of tightness. N0 difficulty will be encountered in tightening the clamping structure, since. the screw 2! may be of sufiicient length to engage the internal threads of the bearing pin before the clamping action ocours, and the head 25 will be restrained from rotation by the projections 28. The large bearing surfaces provided between the collar 23 and the bearing pin 24 preclude any excessive strains being set up, and avoid any tendency to disturb the relative positions of the rail engaging member [4 and the harness strap receiving member l9.

It-will be noted that the harness strap receiving member l9-tends to take a position properly in alinement in accordance with the position assumed' by the harnessstrap. 1 T
